The present application provides a status output method in NAND flash memory, including, setting ALE signal, CLE signal and WE#, signal wherein ALE and/or CLE signal is set to be 1 and WE# signal is set to be 1; when a falling edge of the RE# is detected, outputting LUN status signal of the NAND flash memory. Further, there is provided a NAND flash memory, including I/O signal pins, which includes an ALE signal pin, an CLE signal pin, a WE# signal pin, and a RE# signal pin; wherein when the ALE signal output by the ALE pin and/or CLE signal output by the CLE pin is 1, and WE# signal output by the WE# pin is 1, once a falling edge of the RE# is detected, the LUN status signal of the NAND flash memory is detected.
